The present disclosure relates generally to websites that may be or become infected and, more particularly, to techniques for detecting infected websites.
Websites are susceptible to infection. Malicious hackers may use exploit kits or other techniques to infect websites. The infection may occur by changing a web server's configuration files or content. Some infections manifest themselves to users by redirecting the users to malicious websites. A redirection may be in the form of an HTTP response status code “302 Found” with the URL to which the user should be redirected.
For example, a user may attempt to navigate to a website such as http://www.acme-insecurity.com. In some cases, the infected website might redirect the user to an obviously malicious website such as http://www.malware-makers.com. The malicious website may display unwanted advertising, pornography, violence, or otherwise offensive content. The malicious website may attempt to transfer a virus or other malware to a redirected user. Additionally, redirections may eventually cause degrading machine hygiene as measured by rate or history of infections.
In other cases, the infected website might redirect the user to a more subtle malicious website such as http://www.acme_insecurity.com. In this example, the malicious website is located at an address that uses an underscore instead of the hyphen in the legitimate website address, which a redirected user might not notice. The malicious website may attempt to mimic the legitimate website to trick a redirected user into revealing sensitive or otherwise private information through a phishing or other social engineering attack. For example, the malicious website might attempt to steal a user's password by mimicking or spoofing the legitimate website so that a redirected user may attempt to login before realizing that the malicious website is fake.
Increasingly, websites are infected in such a way that users will be redirected only when certain conditions are satisfied. In some cases, an infected website may contain malicious code that redirects users to a malicious website only if the users arrived at the infected website by way of a particular search engine or social networking website. For example, if a user navigates to http://www.search-engine.com, searches for “Acme Insecurity,” and clicks a link in the search results for http://www.acme-insecurity.com, then the malicious code will detect that the referring website was Search-Engine.com. This referrer may satisfy the condition in the malicious code that triggers a redirect to the malicious website. In contrast, if the user navigates to http://www.acme-insecurity.com directly, then it may not satisfy any of the conditions to trigger a redirect. This user may continue browsing http://www.acme-insecurity.com as if the legitimate website was not infected at all.
Conventional website infection detection techniques may fail to take conditional redirection into account, making it difficult or even impossible for conventional techniques to reproduce, verify, or collect information about a website infection. Additionally, conventional techniques may also be more likely to detect false positives because they fail to determine when a redirect may be intentional by the legitimate website and not a result of an infection.
In view of the foregoing, it may be understood that there may be significant problems and shortcomings associated with current website infection detection technologies.

Referring to
The description below describes network elements, computers, and/or components of a system and method for infected website detection that may include one or more modules. As used herein, the term “module” may be understood to refer to computing software, firmware, hardware, and/or various combinations thereof. Modules, however, are not to be interpreted as software which is not implemented on hardware, firmware, or recorded on a processor readable recordable storage medium (i.e., modules are not software per se). It is noted that the modules are exemplary. The modules may be combined, integrated, separated, and/or duplicated to support various applications. Also, a function described herein as being performed at a particular module may be performed at one or more other modules and/or by one or more other devices instead of or in addition to the function performed at the particular module. Further, the modules may be implemented across multiple devices and/or other components local or remote to one another. Additionally, the modules may be moved from one device and added to another device, and/or may be included in both devices.
According to some embodiments, protected URL management module 312 may manage a list of protected URLs. For example, a security vendor may provide a service to register a website as a protected URL. The protected URL management module 312 may process and track registrations of websites as protected URLs within the security vendor's service. In some embodiments, the infected website detection module 310 will enable detecting infections for websites registered with the protected URL management module 312. In some embodiments, the protected URL management module 312 may maintain contact information for administrators of registered websites to enhance the infection notification services. For example, if an infection is detected in a registered website, the protected URL management module 312 may notify or alert an administrator about the possible infection. The notification may include details about the type, circumstances, severity, or other information about the infection. Additionally, the protected URL management module 312 may allow for a website administrator to designate certain redirections from certain URLs as intentional or safe.
In some embodiments, the protected URL management module 312 may provide information regarding protected URLs to users. For example, a user may be using a security agent from the security vendor. The security agent may be a network security engine such as an intrusion protection system (IPS) engine that can detect or monitor redirects from a protected URL to any other website based on the protected URL information sent by the protected URL management module 312.
According to some embodiments, the redirection report aggregation module 314 may aggregate redirection reports submitted by a plurality of security agents detecting redirects for the user. In some embodiments, the redirection report aggregation module 314 may be in communication with the protected URL management module to determine whether a particular redirection report is analyzed, or whether a particular redirection report contains an intentional and safe redirection. In some embodiments, the redirection report aggregation module 314 may prioritize when a particular redirection report is analyzed based on whether the redirection report contains a redirection from a protected URL.
In some embodiments, the redirection report aggregation module 314 may analyze a redirection report to assess the conditions in which the redirection may have occurred. For example, the redirection report may include a set of site navigation parameters, including HTTP parameters such as the Referrer or the User Agent. The redirection report aggregation module 314 may also analyze conditions across a plurality of redirection reports, such as the time elapsed between subsequent redirection reports. In some embodiments, the redirection report aggregation module 314 may aggregate data across a plurality of redirection reports, analyzing intersections of redirections details from a plurality of redirected users to detect whether a website is infected and determine the conditions that may have been satisfied to trigger the redirection more accurately.
According to some embodiments, the malware report correlation module 316 may be in communication with the redirection report aggregation module 314 to correlate malware reports received from a plurality of users with the redirection reports received from the plurality of users. For example, the user's security agent may also scan for malware on the user's system. A scan may occur periodically, or a scan may be triggered when the security agent detects a redirect. In some embodiments, the malware report correlation module 316 may receive reports from the security agent when malware is first detected on the user's system. A malware report may include information about the circumstances in which the security agent detected the malware. For example, the malware report may include the date and time at which the malware was first detected in the user's system.
In some embodiments, the malware report correlation module 316 may correlate malware reports from users with infections of particular malware to redirection reports from those users redirected from a particular website. The correlation may enable the redirection report aggregation module 314 to detect infected websites more accurately. For example, if users redirected from a particular website are also infected with a particular malware, it may be more likely that the malware infection resulted from a malicious redirection due to a website infection.
In some embodiments, the malware report correlation module 316 may use the date and time information in a malware report to improve the correlation of malware infections with redirections. For example, if a redirection report indicates that a user's security agent detected a redirection at a first time, and the security agent subsequently detected new malware on the system within a predetermined threshold period of time following the redirection, it may be more likely still that the new malware infection resulted from a malicious redirection due to a website infection. For example, the threshold may be one minute, ten minutes, or any length of time suitable to improve the accuracy of correlating malware report information with redirection report information.
According to some embodiments, the redirection protection module 318 may be in communication with the redirection report aggregation module 314 to facilitate protecting users from malicious redirections due to infected websites. For example, the redirection protection module 318 may send information regarding possible infection to users' security agents, which the security agents may use to protect the users from malicious redirection, such as by blocking access to infected websites or redirected users to safe landing websites instead of malicious websites.
In some embodiments, the redirection protection module 318 may include information regarding the conditions that must be satisfied to trigger a malicious redirection for a particular infected website to enable more selective protection. For example, the redirection protection module 318 may report that a particular infected website only causes a malicious redirection when a user the referring website is a particular search engine. With this information, a security agent may selectively permit access to the infected website when the known conditions for triggering a malicious redirection are not satisfied.
Additionally, in SafeWeb, URLs may be marked with security information. In some embodiments, SafeWeb URLs with specific redirect parameters on a given target URL may be marked as a security risk, while URLs without those redirect parameters may be marked as safe.
In some embodiments, the infected website detection module 310 may detect redirections due to malicious advertisements published to advertisement networks. Advertisement networks that fail to prevent malicious advertisement placement may be rated poorly in an advertisement network rating system. In some embodiments, the redirection protection module 318 may send information about an advertising network's rating to the security agents. The security agents may vary the degree of protection when a user encounters an advertising or other content publishing network based on an implied risk associated with a particular rating.
Referring to
At block 404, protected URL information may be sent to security agents for a plurality of users.
At block 406, one or more redirection reports from one or more security agents may be received.
At block 408, one or more malware reports from one or more security agents may be received.
At block 410, the one or more received malware reports may be correlated with the one or more security agents. In some embodiments, correlation may be based on the type of malware reported or the amount of time elapsed between detecting the redirection and detection the malware.
At block 412, information from the one or more received reports may be aggregated, and the aggregated received reports may be analyzed to detect whether a particular website is infected.
At decision block 414, if an infected website was not detected at block 412, then the method 400 may return to block 406 so additional reports may be received for aggregation and analysis. If an infected website was detected at block 412, then the method 400 may proceed to block 416.
At block 416, after an infected website has been detected, one or more conditions that must be satisfied to trigger a malicious redirection may be determined based on the analysis at block 412.
At block 418, redirection protection information may be sent to the security agents. If a condition was determined at block 416, the determined condition may be included as part of the redirection protection information sent to the security agents.
At block 420, if the infected website is a registered protected URL, the contact registered to the infected protected URL may be notified. In some embodiments, if the infected website is not a registered protected URL, an appropriate point of contact may be determined and notified if possible.
After the contact is notified, then the method 400 may return to block 406 so additional reports may be received for aggregation and analysis so that further detection of additional infected websites may proceed.
At this point it should be noted that infected website detection in accordance with the present disclosure as described above may involve the processing of input data and the generation of output data to some extent. This input data processing and output data generation may be implemented in hardware or software. For example, specific electronic components may be employed in a infected website detection module or similar or related circuitry for implementing the functions associated with infected website detection in accordance with the present disclosure as described above. Alternatively, one or more processors operating in accordance with instructions may implement the functions associated with infected website detection in accordance with the present disclosure as described above. If such is the case, it is within the scope of the present disclosure that such instructions may be stored on one or more non-transitory processor readable storage media (e.g., a magnetic disk or other storage medium), or transmitted to one or more processors via one or more signals embodied in one or more carrier waves.
The present disclosure is not to be limited in scope by the specific embodiments described herein. Indeed, other various embodiments of and modifications to the present disclosure, in addition to those described herein, will be apparent to those of ordinary skill in the art from the foregoing description and accompanying drawings. Thus, such other embodiments and modifications are intended to fall within the scope of the present disclosure. Further, although the present disclosure has been described herein in the context of at least one particular implementation in at least one particular environment for at least one particular purpose, those of ordinary skill in the art will recognize that its usefulness is not limited thereto and that the present disclosure may be beneficially implemented in any number of environments for any number of purposes. Accordingly, the claims set forth below should be construed in view of the full breadth and spirit of the present disclosure as described herein.
